Objectives: Oral squamous cell carcinoma (OSCC) is the most common oral malignancy with low survival as it is very often diagnosed at an advanced stage, which is why the accurate profiling of the tumor is essential. The aim of this study was to, for the first time, compare in OSCC the frequency of AR, VEGF, MMP9, HiF1beta and Ki67 between the non-metastatic and metastatic disease. Materials and Methods: In the study, 96 non-metastatic and 91 metastatic OSCC patients were analysed for AR, VEGF, MMP9, HiF1beta and Ki67 levels by immunohistochemistry. Results: All of the tested biomarkers significantly differed between non-metastatic and metastatic disease. A significant association was found between >/=20% AR positive epithelium cells in cytoplasm, Ki67 and VEGF in cancer stroma. Ki67, HiF1beta, VEGF and MMP9 were significantly associated with TNM stages. Conclusion: Our results show for the first time an interplay between AR, VEGF, MMP9, HiF1beta and Ki67 in OSCC which may contribute to better diagnostics and therapy selection.

При плоскоклеточном раке полости рта основной причиной летальных исходов является метастазирование в регионарные лимфатические узлы. Злокачественный рост и формирование метастазов напрямую зависят от степени кровоснабжения первичного очага новообразования. Известно, что по мере прогрессирования опухолевый процесс сопровождается нарушением сбалансированной в норме системы регуляции ангиогенеза с превалированием уровня ангиогенных стимуляторов над ингибиторами. В связи с этим, использование антиангиогенных средств является патофизиологически обоснованным методом борьбы со злокачественным ростом. В обзоре обсуждаются данные доклинических исследований участия эндостатина, природного ингибитора ангиогенеза, в процессах подавления прогрессии и метастазирования плоскоклеточного рака челюстно-лицевой области. Проанализированы патогенетические механизмы ингибирования эндостатином опухолевого роста в экспериментальных моделях рака полости рта. Эндостатин можно рассматривать в качестве потенциального противоопухолевого средства для лечения данной нозологии. The main reason for cancer-associated mortality in patients with oral squamous cell carcinoma is metastatic spread to regional lymph nodes. It is known that the processes of malignant growth and metastasis are highly dependent on blood supply to the primary cancerous focus. The development of malignancy is accompanied by failure of the normally well-balanced system of angiogenesis regulation with prevalence of proangiogenic factors over inhibitors. Therefore, the use of angiogenic inhibitors is a pathophysiologically justified method aimed at suppression of cancer progression. This review presents reports of experimental studies on the role of endostatin, a natural inhibitor of angiogenesis, in processes of tumour shrinkage in squamous cell carcinoma of the maxillofacial region. The authors analysed pathogenic mechanisms of the anticancer effects exhibited by endostatin in preclinical models of oral malignancy. Endostatin can be regarded as a potential antitumor agent for the treatment of oral squamous cell carcinoma.

Aim: Histone acetylation and methylation control gene expression. We investigated the impact of SET knockdown on histone methylation status and the consequences for the miRNAs levels in oral squamous cell carcinoma (OSCC). Methods: OSCC cells with and without SET knockdown were analyzed by quantitative real-time PCR to determine miRNA levels, and by immunoreactions to histone modifications. Results: The knockdown of SET increased the levels of histone H4K20me2 and miR-137. Still, SET protein binds to the miR-137 promoter region. The transfection of miR-137 mimic reduced the KI67 and Rb proteins and proliferation of OSCC cells. Conclusion: Our results show for the first time a relationship between SET and histone methylation associated with the control of miRNA expression and KI67 and Rb as targets of miR-137 in OSCC.

A cross sectional study of 29 cases of oral squamous cell carcinoma with or without  cervical lymph node metastasis was done among Bangladeshi patients from January 2006 to December 2007. Majority of the study subjects (34.5%) belonged to the age group of 40-49 years. 58.6% of the study subjects were male, while remaining 41.4% of them were female. 51.7% of the lesions were located in the alveolar ridge where the other common sites were buccal mucosa (27.6%) and retro molar area (13.8%). Half of the study subjects (51.7%) were habituated to betel quid chewing followed by 37.9% and 10.3% were habituated to smoking and betel quid-smoking respectively. Grade I lesions was most prevalent (75.9%) in the study subjects.  Majority of cases presented with Stage IV lesions (55.2%). The sensitivity, specificity, positive predictive value, negative predictive value & accuracy of clinical palpation method for determining metastatic cervical lymph nodes were 93.33%, 64.29%, 73.68%, 90% and 79.3% respectively. Careful and repeated clinical palpation plays important role in evaluation of cervical lymph nodes though several modern techniques may help additionally in the management of oral cancer.DOI: http://dx.doi.org/10.3329/updcj.v1i2.13978 Update Dent.
